Abstract
Cable modems are devices that allow high-speed access to information at a distant server may it be Internet server or video on demand server, via a cable television network. While similar to the traditional (analog) dialup modems, a cable modem is significantly more powerful, capable of delivering data approximately 500 times faster. During the early to mid - 1990s, the two-way interactive communication capability of the existing cable network infrastructure was realized which would imply a much greater bandwidth for accessing the Internet. This realization resulted in several field trials being conducted in various areas of United States and western European countries. As a result of these field trials, several types of cable modems were developed.
